As `f_0` is also real, similar to `f_(N/2)`, this should of course have
been:
```d
auto fToWave(R)(size_t N,R coefficients_f){
return iota(N/2+1).map!(j=>
tuple!("magnitude","frequency","phase")(
(j==0||j==N/2?1.0:2.0)*abs(coefficients_f[j]).re,
K(j)*sample_rate/N,
std.complex.log(coefficients_f[j]).im)
);
}
```
